His eyes narrowed at the sound of limited idea, because he was entirely far smarter than she made him sound;  & yet he remained silent. What he had wanted was information,  & how many times had he had to remain silent in the face of supporters of the Witch as they spouted insults at him in hopes of breaking him so heâd forget about getting any more information from them? Heâs HONESTLY lost count. So it was not difficult for him to simply walk almost beside her as if his words hadnât partly offended him whilst  m a k i n g  n o t e of every single thing she said.Â
        Granted, when she said box, the only thing the young King could think of was the familiarity of a cardboard box where heâd put books or clothes for safe keeping,  & for a moment he felt as if he were about to jump on a magic carpet  & fly to Kent like one of those stories heâd read in that Arabian nights book;  & truly, heâd only just been about to ask for more information when the familiarity of a police box he had never before seen in the grounds of the school came into sight. Suddenly he felt that she was not ENTIRELY wrong to have used the words âlimited ideaâ when it came to him; his arms uncrossed  & fell to his sides with a rather shocked disposition, because even though he was small, the police box seemed like  t o o  l i t t l e  a space to travel,  & yetâŚÂ
        Was that machinery he had seen within the smallest glance allowed when she stepped inside?Â
        Heâd barely heard her words,  & definitely paid no heed to them, before he started following behind her into the more than unconventional ship he had not even imagined; unlike the time he had gone into the wardrobe for the first time, though, his heart beat WILDLY within his chest in expectation of something inexplicable as he stepped through the blue doors, hoping for the magic he was f a m i l i a r  with, wishing for every single thing that would make returning to Narnia possible,  & bracing himself for any sort of disappointment that could break his heart. Â
        First it was the lights, brighter than any inside the school  & definitely stronger;  & then it was everything else inside the enormous ship that settled into his mind as the little doors closed behind him. There were stairs, there was that giant piece of machinery he didnât understand that he had gotten a small glimpse of before, there were chairs, hallways that surely led SOMEWHERE other than a wall,  & as he stepped along the small hallway away from the door, the true size of everything around him wrapped him within the  f a m i l i a r i t y of the lack of logic of what a small object could hold inside.Â
        Indeed, unlike the first time he had stepped through the wardrobe, Edmund Pevensie fully  & completely smiled,    â Itâs just like with Narnia, â   he said, turning on his step regardless of how he continued walking in the direction of the blonde woman he suddenly held dearer than any stranger since he had met his wife; because suddenly, as the enormity of the shipâs interior befell him, he BELIEVED every single thing she had told him  & even trusted that she would be able to take him back home at once. Perhaps he hadnât believed before, but by Aslan, he  h a d to hold onto the nearest rail because looking up  & around him was making him dizzy,  & still, he couldnât help his smile,Â
        â Is this another land? â   He asked then, turning to look at her regardless of the enormous joy  & hope that surely showed in his expression,    â I mean, I know you said itâs your ship, but⌠I want to know how it works. â   He began to climb the stairs so he could actually stand beside her, curious as much as happy for the first time in what felt like entirely too long,    â Because⌠when I stepped into the wardrobe, it was MUCH bigger inside, too, but it was a whole land, â    he paused,    â A whole world, really; Narniaâs only a country,  & there are many others around it,  & oceans,  & stuff we didnât even have time to  m a p before we left. So, is it the same here? Do you just⌠travel with your whole world around you, or is this some other sort of magic? How big is this place? âÂ
        & just like that, the endless questions had begun.
The Doctor does her best to give the boy a bit of privacy while he runs through the familiar checklist of realizations -- or as much privacy as one can manage while still being in the same room -- busying herself with a readout and a couple buttons that donât do anything useful. Every few seconds, she steals a glance at him out of the corner of her eye, just to make sure that heâs still standing ... and not messing with anything fragile. She doubts heâd manage to do any real damage, but you can never tell with people, especially when they find portals in wardrobes and are much older than they seem. After all, sheâs a good bit older than she looks, too, and she can break anything if sheâs given enough time. Broke the entire universe once. That was a bad day.Â
Even when he starts asking questions, she still keeps the majority of her focus on the TARDIS itself. âItâs kind of a land,â she replies, wrinkling her nose and looking up at the ceiling. âItâs not on land, exactly, but thereâs a floor, and gravity orientation, and no oceans to speak of,â her voice trails off as she wanders further and further away from the point, brow furrowing as she catches herself thinking more and more about the logistics of putting an entire world, with an independent notion of time, in a single piece of furniture. A few explanations come to mind, all equally plausible and implausible at the same time, but sheâs not going to be able to know for certain until she steps into that world herself.Â
          If she can actually manage to get them there.Â
âTransdimensional engineering. You fold a bigger space into a smaller space. Bit complicated, way past your time.â Sheâs tried to explain it before, with boxes and metaphors and a dozen other things that make sense to Time Lords, but humans never really seem to grasp it, probably because theyâve never done it. She understands. She couldnât latch onto anything theoretical while she was a student at the Academy. It was only when she stole a TARDIS and began gallivanting across the universe that she really began to pick up on things and retain information in the way that had seemed natural to everyone else in her classmates. It had been too late to help her pass her exams, but it helps her through life, and as far as sheâs concerned, thatâs far more important.Â
âNow that thatâs settled,â she starts, fully aware that it takes much, much longer for people to shake themselves free from the shock of seeing the inside of the TARDIS for the first time, "Best that you can, can you tell me where the house with the wardrobe is? Or who owned it. I can do a reverse address lookup from there, if I need to.âÂ
Not that she wants to. She doesnât like getting bogged down in the details. Better to just point the ship in the generally right direction and hope.Â
